-To c/,ZZ 'wzomz't may concern Be it known that l, CHARLES C. STU'm,

residing atv Norwood, in the county of Hanr 2 ilton and 'State of01110,.. a citizen ol theV United States, have invented or discovered ycertain, neuY and useful 'Improvements in Machines foryGathering Glass,of which iinprovements the following is a specification.

As' is Well known ylo those ,skilledv in the art it'isimpracticable togather glass'by a i' ladle or rod 'from 4a molten mass Without? 'theform-ation of strands extending from the gather to' the mass of glass.'When this l strand is severed a. portion drops back into Athe mass andit requires time for such re- Z- turned portion to become'incorporatedwith i And further the rod or ladle being colder than vtheglass, portions of the.: glass adjacent to-the vpoint of immersion of"Vthe mass.

the ladle or rod'r become chille(1 to suclia degree, that if a secondgather is made-im? 1 mediately at the saine point as the 'firs-t theglass of the second .gather Will lack uni-f formity andlines, etc.,Willappear inthe article formed therefrom.

employed for shift-ing vthe swinging the ladle 9 iscarried byrodlOhaving its i rear 'end niovabljy' lmounted in a sleeve 'll which is`provided with trunnions having their journals mount-edili4 notches inthe arms 13. These arms are secured to the swinging' member 4 which yis'pivotally mounted on the upper slide 5 .mounted on the slidefl. Thisslide il, is in turn mounted on a frame G which may be stationaryv ormay be reciprocated dependent. on the number and arrangement of molds tob'e'charged as clearl)7 shown and' described in the Let- The upper ortoolV slide is reciprocated by screwv S which is .preferably rotated 'bymechanism substantially7 similar to that employed in the patentedmachine and the lovver or tool tipping slide 4- is moved vforward b vthe slide 5 through 'the medium of springsjld, so that the slide 5mayiuove independent' of slide 4 as, will be hereinafter described. Therearward movement of the slide 4 is also etlectedbj slide 5 by means ofa stop 1S on slide engaging a. por-tion of slide 4 or in anyY othersuitable manner.

AThe tool carrying sleeve ll is provided with an angularl)Y arranged arm14 pro .vided atj'its loxveizend with lateral projections, preferabliTin ther form *ofV rollers engaging guide Ways l5, which is carriewi on aslide i9 mounted on a'curved guide 2001i the front end of the loiversli-de 4, the center of curvature of the ouide coinciding with thecenter of movement of the swinging member 4: -As will be seen byreference to Figs. l to '-1 the arms 13 on which thelacre is carried'While being shifted back and forth, extend through slots 2l in theslide 19, thus insuring coincident and equal movements of the slide "i9and the swinging As fully set. forth in the pan. referred to the slides5 el move fore/*ard together until t? means ladle oi7erftheglass supply,at'which time the further movement i afield@ abad In the embodiment ofmy invention which is adapted for supplying molds arranged in tandem as'shownand described in. the patent referred to, the gathering" of glassis eected on opposite lsides, of thel line `on which the molds arearranged and hence provision is made'V for shifting the swinging member4a and the tool carrying rod to oneside o r the other of the line onwhich the molds are arranged, as the slides 4 and' 5 move forward, andto bring said parts into alinement with the molds after the for shiftingthe swinging member "consists of arms 22 so pivotally mounted lat theforward ends of guides 23 that lwhen in midposition the inner edges ofthese arms will be in alinement with the inner edges of the guides ontowhich rollers 24 will be directed by the arms as the slides 4 and 5 moveback. The arms -are-provided with angular extensions 25 to which areconnected rods 26 provided at their rear ends with straps surroundingeccentrics 27 oppositely secured on shaft 28. On this shaft 28 isloosely mountl ed apinion 29, which when rotated in one ldirection willeffect theI .rotation of the shaft through the medium of a pawl 30.

Thispawl ismounted ina recess in the inion in such manner as to engageshoulders on the shaft, as shown in Figs. 6 and 7 The reverse movementof the pinion on the shaft is effected by a spring 31. This pinion isoperated to shift the eccentrics27 by a rack' 82 which is pushed back bythe slide 5 as it approaches the rearward limit of its movement. rIherelative arrangement of the shoulders on the shaft and th'e movementimparted to the rack by the slide 5 will depend uponpthelateral movementto be imparted to the gathering tool for the succeeding gather. By theshifting of the eccentrics the arms-22 are shifted from one position tothe other, while the slide 4 is in its rear position, so that whenduring the next forward movement of the slide, the rollers 24 move intothe arms, the swinging member 4a, the ladle rod, the slide 19, etc. willbe shifted to one side of the, median l line of the machine.

While the rotation of the gatherin tool to collect the molten glass maybe e ect'ed employ the means set forth in the patent referred to andshown in Figs. 1, 3 land 4. On the rear end of the rod 10 is secured adrum 56 to which are attached two `straps 57 passing in oppositedirections to a second drum 5S .loosely mounted on the stud 59 securedto the arm 14.- A disk.60 is secured to the drum and is connected by auniversal joint 61 .to one member of a telescopic shaft consisting of arod 62 and-a sleeve (S3-keyed one 'to the other so as to rotate inunison but to move longitudinally independently one of the other. Thesleeve 63 is connected by a universal joint 64 to a short shaft`mounted. .in the rear end -of the upper slide 5. A sprocket .wheel 65on this shaft is operatively connected by a chain tol a corre-' spondingwheel 66l so mounted on the shaft A6( which extends the full length ofthe machine, as to be rotated thereby and movable along theA same by theslide A5. A 'It will be readily understood that ifthe intervals of timebetween successive gathers are sufficiently long to permit of therestoration of the molten glass to normal or workingcondition, only twochanges of position ofthe gathering tool will be necessary. But asinmost cases the time interval between successive gathersl will be tooshort for a.

4p'roperrestorat-i'on of the glass,provision is made for other changesvofthe position of the tool in gathering.- As for example the depth ofmovement of the tool into the furnace' or its forward movement over theglass supply may be changed for,l the second, gather following a lateralchange of position as above described. This change in thev extent ofmovement of .the tool is effected by varying the forward movement of theslides 4 and 5. In the construction 'shown herein, the movement'of theslides is effected vby the screw 8, as hereinbeforestated. The

construction for' rotating the vscrew 8 is preferably as set forth inthe patent referred to, zi'. e. a pinion on the screw is driven througha sprocket chain 150 by a pinion on the lshaft 151, ywhich is operatedthrough suitable gearing by the motor driven shaft The stopping,starting and direction of movement of the shaft 151 and consequently ofthel slides 4 and 5 is controlled by cam grooves on the drum 169, andconnections fromsaid 'grooves to starting and reversing'clutches asfully shown and vdescribed in said patent. In theembodiment of theinvention set forth herein a dipping or gathering cycle will involvetwolong and two short strokes or movements ofthe slidesv 5 and 4 andconsequently the grooves in the drum 169 are constructed for four-'periods'.

But when using my' improved gathering.

mechanism in connection with a three unit shaping machine as shown anddescribed in the patent referred to, the frame 6 will `be vshift'edonlytwo times during a dipping cyele. as said frame is not moved when thefirst mold of the. series is charged. As in the patent, this slide isieciprocated preferably by a threaded shaft-.145, driven 4from shaft SiLwhich has jkeyed thereon 'a pinion HG intermeshing Vwith a pinion 147looselyvniounted on shaftl ll'fbut adapted to be operatively connectedthereto by -a Clutch 14:8.' This clutch is shifted by cam 169?.- Thiscam is loosely mounted-'on a stud'aiid is adapted to bev rotated througha sprocket chain by a vsprooket. wheel 3 4 on the shaft'e'arrying thedrum .169. The ineclia-. nism operating the threaded shaft- M5 issooonsti'iioted and driven, that tlie'p'fra'me 6 will shifted. duringtwo dipping or gathering' movements, but will be stationary during thethird gathering and mold charging movements V i The movement of tlietooldown to gather glass is effected by checking-the movement ot' tlieloiverslide Ll' While the upper slide continues itsforward movement, The stopping of the forward Amovement of the 'lovver-V oi'- tipping slide isetieeted. bysuitahle stops,l

the position of one of ivhich must be ol-ianged to correspond with vthechange "inthe foi'- vward-movement of the slides lieieiiibeforedescribed. and also to jvary .the ldovvnimi'tl movement of the tool,as'the level ofthe glass in the supply changes. struction shown, I whichis preferred altho'u gli other forms may beused, the niecl-'ianisni for'arresting slide feat-the endsjof the shorter tool movements is carriedin part by said slide and in p art'byl the frame (3. Theelements'earried by the slidel .consist ofpa nutprovided with a lateralextension and -inonnted on a threaded .sleeve'BG through v portedinbearings 3S secured to the frame which passes a rod 3.7 having its endssup of the machine. The, ends of the sleeve are so held iii lugs 3S?, onthe slide'las to move v the sleeve along the rod 3T but permitting thesleeve to be rotated by the rod, to which dit is splined, foradjustingvthe position of the nut.V The other elements ofthe stop Iiiechanisin`consists of a vertically movable slide l() .provided with a pi'.tijettin -ll eX.,- teiiding vinto a cam groove in'the disli 42 loosely mountedon the stud 43.' The rotation of the dish to move the slide into and ontofthe ,path of movement' of the-nut or Y stop member 33 is elfected bythe shaft 2S .throngh suitable sprocket Wheels' lie and chain l5. asshown iii Fig. G. Thefgroove in disk l2 is lso constructed, and the'disk is so rotated that the slide -lO' will extend into the path ofmovement of Athe stop l5 during two sucrev e forward moveinc ts of theslides l and 3 and will he ivi'thdraivn during the -next tvvoior longerforward movements of the slide -..l-, which is then stopped to dip thetool by tile fixed Stop lli.

it is characteristic of my iniprovementl va ryiii g the that the point.tif-gather an be'varied 'either by .sliifthigthe tool carrying deviceslaterally or by vary-'nig the length of .sti'okeof sueh devices, andythat by suitably combiningy such change producing means of position a'plurality of pointsof gathering -iiiay vbeobf'l vtaiiiethaiid in that"any rendering it. possible between suoto reduce the intervals of timecessive gathers.4

[t will be iiiiderstoodvthat suitable means are to be employed 'forremoving the glass' from the gathering tool andtraiisterring'it to themolds. is for example ivhe'n using my improvements in connection iviththe apvparatjus shoivii' and described 'lii the patent referred to theglass-may be charged into the molds 'iii the manner therein set forth.'l`he'movenient" necessary to gather the glass is imparted to the toolin any suitable inaniier after the' latter Ahas beenv brought intooperative relation to the glass supply.'
